| Module Parameters | |
| ----------------- | |
| * bus_speed (unsigned int) | |
| Allows changing of the bus speed. Normally, the bus speed is set by the BIOS | |
| and never needs to be changed. However, some SMBus analyzers are too slow for | |
| monitoring the bus during debug, thus the need for this module parameter. | |
| Specify the bus speed in kHz. | |
| Available bus frequency settings: | |
| ==== ========= | |
| 0 no change | |
| 80 kHz | |
| 100 kHz | |
| 400 kHz | |
| 1000 kHz | |

| Description | |
| ----------- | |
| The S12xx series of SOCs have a pair of integrated SMBus 2.0 controllers | |
| targeted primarily at the microserver and storage markets. | |
| The S12xx series contain a pair of PCI functions. An output of lspci will show | |
| something similar to the following:: | |
| 00:13.0 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 0 | |
| 00:13.1 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 1 |
